WINDOW-SHIELD.

Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed February 28, 1910. Serial No. 546,335.

To all whom, it may concern Be it known that I, DANIEL O. N. BALD- WIN, a citizen of the United States, residing at Cleveland, in. the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Window- Shields, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to devices for shielding the windows of street cars, locomotives, or other like vehicles, or the so called wind shields of auto-mobiles. In fact, a device of the character set forth herein is applicable toany window or sight opening which it is desired to protect from sleet, snow or other material which might accumulate thereon and obstruct the vision therethrough.

Among the objects of the invention are the provision of a device of this character which is capable of convenient application to and removal from the window or sight opening with which it is to be employedyralso the.

provision of a device of this character which is capable of convenient adjustment for height to accommodate different observers.

A further object of the invention is to provide a device of this kind which shall be extremely eflicicnt in operation, while being relatively simple and inexpenslve of production.

In the embodiment of my invention disclosed in the drawing forming part hereof,- Figure 1 reprcscnts a perspective View of a portion of a window having my device applied thereto; Fig. 2, a vertical sectional view taken through the window and device shown in Fig. 1; Fig. 3, an enlarged sectional detail of the means by which my device may be adjustably secured to a window or sight opening; and Fig. l, a detail of the connection between one of the shield plates and the casing.

Describing the various parts in the drawing by reference cl'laracters, 1 denotes the frame of a window or similar observation device, and 2 the glass or other transparent medium carried by the frame. Secured in operative relation to the window is the rear or base of the casing 3 of my device. This casing is preferably of sheet metal and is conveniently made rectangular in section. The rear end of the casing is flanged outwardly and inwardly to form a recess, as shown at 4, and is provided with an additional lateral flange 5 by means of which the casing may be attached, as by rivets 6 to a frame 7 of heavier material. This has a central opening corresponding approximately in size to the internal area of thecasing 3 and the frame projects inwardly substantially as far as the interior of the inner wall of the casing 3, forming a groove with the recess 4 for the reception of a pane or plate 8 of glass or other transparent material. The inner face of the frame 7 has applied thereto a packin ring or gasket 9, of rubber or other suita le material, being secured to the frame and to the flange 5 by means of the rivets 6.

For the purpose of securing the device to the window with which it is to be used, the frame 7 will be conveniently provided with a lateral extension 7. As a means for providing a vertical adjustment between the extension 7 and the window frame, the construction shown in the drawing may be employed. In this construction, the window frame is shown as provided with a vertically-extending rod 10 having its ends projecting inwardly and secured to the frame, as shown at 11. The end of the extension 7 is provided with a sleeve 12 mounted on said rod. Between the rod 10 and the inner edge of the window frame, the latter is provided with a vertical slot '13. The outer end of the extension 7 is projected outwardly, as shown at 7 a suthcient distance to clear the outer surface of the window frame, with its inner surface in close proximity to such outer surface of the frame. A bolt 14; extends through 7 and through the slot 13, the bolt having a head 15 bearing against the outer surface of the extension 7 and having on the inner side of the frame a washer 16 adapted to bear against said frame on opposite sides of the slot 13, the inner end of the bolt being provided with a wing nut 17 by means of which the washer may be tightened against; the inner side of the frame. The construction described provides an extremoly efiicient and convenient means whereby the device maybe adjusted at will and secured in adjuste osition.

For the purpose of shielding the window to which my device is applied, I provide the casing 3 Wltlltll following structural feerame tures:-At its outer end the casing is provided with a plate projecting downwardly and forwardly from the upper wall thereof at an angle of about r5 or other suitable angle, said plate being shown as an apron 18. The casing 3 may be conveniently formed from a single sheet of metal with the outer edge 19 of the bottom directly below the upper edge of the apron 18, whereby the apron overhangs the bottom. The apron 18 extends downwardly approximately half the distance between the top and bottom of the casing 3, and is provided on its inner surface with a'mirror 20, which may be secured in place in any convenient manner, as by bending the lower end of the apron around the lower end of the mirror, securing the upper end in place by means of the metallic clamp 21.

The bottom wall of the casing is provided with a transverse slot 22 through the rear of which projects a plate 23, said plate being pivotally supported by the casing. A convenient manner of so pivoting the plate is illustrated in the drawings and comprises a transverse rod 24 fitting in a corresponding recess in the plate. This plate is provided with a pair ofside flanges 25, located each at an edge of the plate and extending above the bottom of the casing and the slot formed therein. The flanges 25 cooperate with the opposite ends of the plate 23 and the opposite ends of the slot 22 to form a discharge chute for the air admitted to the front of the casing.

For the purpose ofv adjusting the angle which this plate makes with the bottom of the casing, the side flanges may each be provided with a suitable projection 26, conveniently pressed therefrom and adapted to enter recesses 27 in the casing wall. In

, stormy weather, the plate will generally be secured in the position shown in full lines in Fig. 2, namely, extending over the slot 22 at an angle of about 45 with the bottom of the casing. The plate will be of such extent that, when in this position, its upper edge will be about midway of the height of the casing, or on a line drawn from the lower edge of the apron 18 to a point half way between the top and bot-tom of the glass 8. The slot 22 will preferably be located nearer the rear end of the casing 3 than the front end of the same.

28 denotes a downwardly-inclined plate secured to the upper wall of the casing and projecting downwardly and rear'wardly at an angle of about 45 and preferably in the plane of the late 23 when the latter is in the position s own in full lines in Fig. 2. Between the plate 28 and the rear of the casing there is located a plate, 29 which is secured to the upper wall of the casing and projects downwardly, preferably in vertical alinement with the upper edge of the plate 23 when the latter is in the position shown in full lines in Fig. 2.

In operation, the device will be adjusted so that the eye of the observer will be at about the point 30. It will be observed thatlines drawn from this point to the lower edge of the apron 18 and to the outer edge of the bottom of the casing will respectively cut the lower ends of the plates 28 and 2 9 and the upper end of the plate 23. It thus follows that, with the eye at the point 30, the plates 24, 28 and 29 will not interfere with the field of vision. The apron 18 protects the upper portion of the casing against the entrance of snow, sleet, or other matter which might interfere with the Vision. The plate 23 protects the lower part of the easing, adjacent to the glass 8, against the admission of such material. The apron and plate prevent any material entering the easing and moving in a straight line from getting into the chamber at the rear of said plate. The plates 23 and 29 form in effect a dead air space or cushion" at the rear of the casing, which will prevent snow, sleet, etc., from entering the space behind the plates through the eddying action of the air cur rents. Should any material be carried beyond the lower end of the plate 28, it will probably be dropped into the space in front of the-plate 23 before reaching the opening formed between this plate and the plate 29 thereabove. Furthermore, the provision of the slot 22, with the inclined plate 23, tends to carry out any material that may enter the front of the casing. More or less eddying of the air will occur at the front of the window to which my device is attached. This eddying around the vicinity of the outlet slot 22 and the downward inclination of the plate 23 below such slot will facilitate the flow of air through said slot from the front of the casing as indicated by the arrows. This action a so serves to oppose the entry of snow or other material into the chamber behind the plate 23. In fair weather, the plate 23 may be swung into the position shown in dotted lines in Fig. 2 and be retained in such position by the frictional engagement of the projections 27 with the recesses 0f the flanges 22.

As the field of vision will be limited in the manner indicated by the lines from the point 30, the mirror 20 is provided for the purpose of enabling the observer to see objects that may be dangerously near the vehicle to which my device may be applied. This is important in the operation of rapidly-moving vehicles, as it will enable the operator to avoid striking pedestrians or obstructions which may be out of vision defined by the lines extending from the point 30.

It will be noted that the construction of the inner end of the device provides an air chamber 31 between the pane Send the winbetween the apartment or space at the rear of the window and the temperature which exists in front of the pane 8 from producing condensation on and fro-sting of these surfaces. Furthermore, the construction of the frame at the rear end of the casing, including the gasket- 9, prevents snow, rain or other moisture on the surface 2 from entering the space bounded bv the frame, keeping the sight" clear.
